` The present invention relates to the provi# sion vof a whe'el'wherebyharmful effects of roadis'hock and vibration are eliminated and at theSametime thefnecessity for maintain'-y ing pneumatic tires is dispensedwith.

In accordance with the invention the wheel f kconsists ofan outerperipherallor rimsection andan inner or hub sectionencircled by andspaced inwardly from'the rnn section, and

apneumaticpad between the sections pref- ,erablyk secured toboth-sections, the sections being provided with guidingvmeans wherebyvknocking down for replacement, repairs,'etc.

In the accompanying drawings I .haveillustrated an elastic wheelembodying the features of my invention in what is at ypres-y entregarded Aasthepreferredform.

In Ythe drawings :r F Figure 1 is a fragmentary radial section of 'the'wheel. Y

Figure 2 is a fragmentary top plan'of the hub ring. y

Figure 3 is a `fragmentary elevation of the hub supporting plate.

j Figure 5 is an elevation ofthe hubring and hub plate looking from the4left in Figure 1. Figure6 is a view of the same looking from theleft inFigure. Y' Y InFigures 1, 2, '3, 4. and 6 I have illus.- trated a wheelof this type. This wheel'has an outer or rim sect-ion 110, an inner orhub section `111Iencircled`by and spacedinivardly from the rimsectionto.permit radial vmotion of onev relatively to the other, and a pneumaticvpad 112'l between the sections which are Ymaintainedi'n the same radialplane `by cover and guiderplates 114. Y

i yThis structure differs fromthat previously patented by me' intheconstruction of the hub member or section, whereby, it may be madeVentirely of sheet metal which maybe cold rolledor stamped into shape.

The hub member consistsof a .hub ring 1 1'6`which may becold rolled orformed in any suitahleway, a hub plate 117 in the formof a flat annularplate which may beof sheet metal or other material, la bead holding ring11S engaging the inner bead 119 of the pad 112 land bead holding and hubsupporting f UNII'IEnf sfrnrns PATENT) OFFICE plat-e120 which assistsinv supporting the hub ring'116and also engages the bead 119 after themanner of one sideofa clincher rim.. The bead ring 118 and the bead 119ofthe pad are held in position by bolts 121 placed at suitable intervalsabout the periphery of thehub parallel to the axis. To receive and holdthese bolts the hub ring 116 is gro'oved or fluted at intervals as shownat 122, being turned inwardly as to the inward surface and depressed asto the outer surface forming protuberances on the inner face of thering.

The hub plate 117` is driven or otherwise forced into position withinthe hub ring 116 being, in the form ofrthe invention shown,

. locked against/rotation therein by means of liutes 122 forming theinner surfaces vof the grooves or apertures, partially encompassing thebolts 121. To engage theseliutes-the plate is correspondingly notched atl123. This plate is further held in positiontby slotted and deectedportions or lips 124, ysee F ig-k ures land 4to 6, formed by displacinginwardly on each side lof the plate small areas ofthe hub ring 116. Thismay be accom` plished by slotting the ring 116 at intervals closeitoeach side of the plate 11'?, as shown in Figures 1 and 4 to 6, anddepressing the material adjacent the slots on each side of the plateinwardlyin ythe direction of the radius ofthe ring so as toformabutments 124cm each side of hubplate 117.

s The hub ring 116 is supported on the Wheel hub in any:suitablemann-er. In the form ofthe invention shown, the hub plate117-issecuredito the hub flange 131 by bolts 132 parallel toithe axisand nuts 135. These. bolts are spaced along the inner peripheral portionof the hubplate, which'is aperturedat 133 in registration with apertures134m the engageY the bolts 132 outside the plate 120, be-

`ing tightened up againstthe latter to hold it in position.

f'lhe hub ring 116 is further supported'by" the hub supporting and beadlockingring 120. This ring 1s slotted at 127 on a cirinside of the hubring 116' and supporting 1 iips 128 are formed b'ydetlecting inwardlyAthe metal adjacent the slots o n the inside. These lips 128 in theassembledV position of Y the plate engage the hub ring from within,

supporting the latter.

e' The outer edge '139 of-lthei'plate 120 isV crimped or turnedoutwardly forming a bead engaging ribl 140 between which and the beadengaging ring 118 the inner bead 119 of the pad 112 is held by bolts'121, as previously v described. YThe pads 1 are coveredV by coverand'guide plates 114,9which are secured to the i hub structure bybolts121 and bear at their outer edge portions 141 against radial liat sur--iiaces 142 on the inner riin 143 of the outer or rim section 110,holding the' latter in ra-Y dial'alignment and permitting motion Vof thehub relatively to the outer rim or rim Y by Letters Patent is:

member inV aradial plane. The hubV ring may be butt ended as shown inVFigure 5 and secured by spot welding the ends 145 to a' short underlyingplate or block 146. The advantages of the sheet metal constructiondescribed as to cheapness of construction,

lightness and increasedfstrength and tough-` ness,will be easilyappreciated.
